So my cycle seems to have stalled at high nitrates. Help please? :D

It's a BH-1000.
And I know, but it is just chemistry for the most part. It is either I try a desperate attempt to get the nitrates down or my tank ends up crashing due to nitrates.

As of today with the skimmer going full steam, day 5 of vodka dosing and no foam in my filter no changes have occurred. This is really frustrating.
